"Is there any value in a 2nd EPIRB
Well, ignoring the fact that AC had a somewhat embarrassing recal some years ago when one of their models showed a test light but actually was not transmitting? Oops, yes, sometimes EPRIBs are defective. If you are buying
a new one, look for one that can send actual test messages to confirm the entire unit is actually working.
And there's still a reason to buy two. If your EPIRB
is packed in the raft, you can be sure it will be there if you need to enter the raft from the water
. Anything you need to carry with you, may be lost
. But if it is packed in the raft and there's only one...you can't get to it without deploying the raft.
So ignoring reliability
, yes, there's reason to own two of them. Two sets of SOLAS-rated flares, etc. as well, for the same reason.
